But she had sworn never to unite herself with any but upon three conditions. First, he was to state accurately and succinctly how many feet there were in the length, breadth, and depth of the four elements. Secondly, what would change the north wind. And thirdly, by what means fire might be carried in the bosom without injury. When the king, therefore, understood his daughter's resolution, he proclaimed it through the kingdom, and promised to give her in marriage to whomsoever performed the conditions. Many endeavoured, but failed; until at length a certain soldier from foreign parts heard of the girl's oath. He hastened to the palace, conveying with him a single attendant, and an extremely fiery horse. On being admitted into the king's presence, he said, "I am desirous of espousing your majesty's daughter, and I am prepared to solve the questions which have been proposed." The king assented, and the soldier calling his servant, commanded him to lie upon the earth. And when he was thus laid, his master measured his length from one extremity to the other.
